Bentonite 100g

The Miracle Clay

It is very effective in dragging out yeast, tannins and other stubborn protein-based particles that may want to linger after fermentation. The result is a wine, mead etc with a glassy clear appearance and a colour that is radiant.

For a 5 litre batch of wine or mead : 2.5 to 5 grams of bentonite

That works out to roughly : 0.5 to 1g per litre

Light fining: 2.5 – 3g per 5L

Cloudy/stubborn batch: 4–5g per 5L

Instructions:

Mix the bentonite first in warm water
Use about 10–20 times its weight in water

Let it hydrate for a few hours, or overnight if you can

Stir it into the mead/wine well

Leave it several days to a week to settle

Rack off the sediment

Important note:

Too much bentonite can strip aroma and flavour, especially in mead

Mead often needs a bit less than grape wine, so I’d usually start around 2.5–3g for 5 Litres

Bentonite is an absorbent aluminium phyllosilicate clay consisting mainly of montmorillonite, formed from volcanic ash. Known as "The Miracle Clay," it is widely used for industrial sealing, drilling mud, skincare, and agricultural soil improvement due to its high swelling capacity, adsorption properties.
